Up to half of women over the age of 80 and a third of medical students describe at least one event at some point in their lives. [7] Of those presenting with syncope to an emergency department, about 4% died in the next 30 days. [1] The risk of a poor outcome, however, depends very much on the underlying cause. [2]
The single most important predictor is fainting or near-fainting during exercise, which should require detailed explanation and investigation. [2] The victims include many well-known names, especially in professional association football, and close relatives are often at risk for similar cardiac problems.
[2] [4] If this is insufficient for treating vasovagal syncope, medications such as midodrine or fludrocortisone may be tried. [4] Occasionally, a cardiac pacemaker may be used as treatment. [2] Reflex syncope affects at least 1 in 1,000 people per year. [1] It is the most common type of syncope, making up more than 50% of all cases. [2]
The lifetime risk is three times greater in men (12.3%) than women (4.2%) based on analysis of the Framingham Heart Study. [149] This gender difference disappeared beyond 85 years of age. [ 150 ] Around half of these individuals are younger than 65 years of age.
They were widely used in Victorian Britain to revive fainting women, and in some areas, constables would carry a container of them for that purpose. [10] At that time, smelling salts were commonly dissolved with perfume in vinegar or alcohol and soaked onto a sponge, which was then carried on the person in a decorative container called a ...
Fainting while remaining vertical increases the risk of death from cerebral hypoxia. [1] Since there is no evidence that these effects are specifically due to trauma, or caused by the harness itself, climbing medicine authorities have argued against the terminology of suspension trauma or harness hang syndrome and instead termed this simply ...
Heat syncope is fainting or dizziness as a result of overheating (syncope is the medical term for fainting). It is a type of heat illness. The basic symptom of heat syncope is fainting, with or without mental confusion. [1] Heat syncope is caused by peripheral vessel dilation, resulting in diminished blood flow to the brain and dehydration.
The prognosis is improved if clinical death is caused by hypothermia rather than occurring prior to it; in 1999, 29-year-old Swedish woman Anna Bågenholm spent 80 minutes trapped in ice and survived with a near full recovery from a 13.7 °C core body temperature. It is said in emergency medicine that "nobody is dead until they are warm and dead."
